And since the Python slowdown comes from a single weird function, I think

Do I interpret correctly?
If (and only if) Fedora switches to -fno-omit-frame-pointer, python3.11 (and
possibly older Pythons) will explicitly use -fomit-frame-pointer instead (aka
opt-out).
Yes. If the change allows software to opt out (e.g. if it's slowed down too
much), then, based on the benchmarks, Python 3.11 should do that.
python3.11 has opted out.
I've also prepared pull requests for python3.{6..10} to do the same.
I don't intent to touch Python 2.7 unless I have to.
No idea how this affects PyPys, so keeping them untouched as well.
python3.12 will do the same for now.
Or not, if that would help testing. I don't think the speed of the preview
Python matters that much.
python3.12 has not opted out.
